What Is The Sacroiliac Joint?
The Sacroiliac joints are located at the very bottom of your back. You have one
either side of your spine.
The sacroiliac joints link your pelvis to the lower spine. They're made up of the
sacrum, which is the bony structure above your tail-bone and below your lower
vertebrae and the top part of your pelvis. You have sacroiliac joints in both the
right and left sides of your lower back. Strong ligaments hold these joints in
place. It is the sacroiliac joints that support the weight of your upper body when
you stand up.
What Is The Function Of The Sacroiliac Joint?
The function of your sacroiliac joints is to allow twisting movements when you
move your legs. The legs act like long levers and without the sacroiliac joints,
which allow these small movements, the pelvis would be at higher risk of a
Lower back pain caused by sacroiliac joints can be difficult to treat due to the
complex anatomy and movement patterns of these joints.
Sacroiliac joint dysfunction is a term often used for sacroiliac injuries and
refers to either the joint becoming locked or being too mobile. This may cause
problems with ligaments and muscles, causing painful symptoms throughout
your lower back, buttocks, thighs or groin.
What are the Symptoms of Sacroiliac Joint Injury?
The symptoms may include:
•Pain located either to the left or right of your lower back. The pain can range
from an ache to a sharp pain which can restrict movement.
•The pain may radiate out into your buttocks and low back and will often radiate
to the front into the groin. Occasionally it is responsible for pain in the testicles
•Occasionally there may be referred pain into the lower limb which can be
mistaken for sciatica.
•Classic symptoms are difficulty turning over in bed, struggling to put on shoes
and socks and pain getting your legs in and out of the car.
•Stiffness in the lower back when getting up after sitting for long periods and
when getting up from bed in the morning.
•Aching to one side of your lower back when driving long distances.
•There may be tenderness on palpating the ligaments which surround the joint.
What Are The Causes of Sacroiliac Pain?
The Causes of Sacroiliac joint pain can be split into four groups:
•Inflammatory joint disease
Traumatic injuries to the sacroiliac joint are caused when there is a sudden
impact which 'jolts' the joint. A common example is landing on the buttocks. This
kind of injury usually causes damage to the ligaments which support the joint.
Pain due to bio-mechanical injuries will usually come on over a period of time
and often with increased activity or a change in occupation/sport etc. The most
common bio-mechanical problems include:
•Leg length discrepancy
Hormonal changes, most notably during pregnancy can cause sacroiliac pain. In
preparation for giving birth, the ligaments of the pelvis especially increase in
laxity. Combining this with an increase in weight putting extra strain on the
spine, may lead to mechanical changes which can result in pain.
Inflammatory Joint Disease
Spondyloarthropathies are inflammatory conditions which can affect your spine.
These may include Ankylosing Spondylitis which is the most common
inflammatory condition to cause sacroiliac joint pain joint pain. Thermal
underpants can help ease the pain and offer gentle support to your lower back.
